I borrowed an S200 for a week and really liked it. So I go into the store to buy one and got sidetracked on a Pentax Option 330RS which was the same size but had more of an array of features and the 3x zoom. I took it back today (because of poor picture quality) and bought the S200 and I am very happy. The main reason for buying the S200 is the size. I can just put it in my pocket and go. I had a look at the S330 but it feels noticably bigger in my pocket so I stuck with the S200.
